Zoomi is a screen magnification accessibility app that helps people with low
vision, presbyopia, and other visual difficulties read what is on their phone.
One floating button adjusts the magnifier and the text size right away, so you
never have to dig through Settings when the text is too small.
■ Why Zoomi uses the accessibility service
Zoomi uses the Android AccessibilityService API because screen magnification
can only be provided through that permission. It is used solely to turn the
magnifier window on and off, adjust the zoom level, and show the control
buttons on screen.
■ Two tools
Screen zoom (magnifier)
Opens a magnifier window over the part you are reading. Adjust the zoom across
9 levels and drag the window wherever you need it.
Bigger text
Raises the system font size across 9 levels, so messages, news and chat apps
all become easier to read.
■ Who it is for
• People with low vision who struggle to make out text on screen
• People with presbyopia who cannot read small print without reading glasses
• People whose declining eyesight makes them miss subtitles or text in photos
• Family members setting up a magnification tool for a relative with visual difficulties
■ Built to be simple
• Drag the button anywhere; it shrinks on its own when you are done
• Open it instantly from the accessibility button at the bottom of the screen
• Your settings stay exactly where you left them
■ Private by design
Zoomi never reads or stores what is on your screen. It does not declare the
permission to read screen content (canRetrieveWindowContent), so it is
technically unable to read the text or images you are looking at.
No code we wrote sends anything over the internet.
(The internet permission you see in app info belongs to the Google Play Billing
Library, which handles the paid unlock.)
